semi-discrete optimal transport for Curvling


DOI

This codes are the implementation of the following paper. It allows to compute the exact optimal transport between a continuous measure (with density) and measure carried by a set of Dirac masses. This toolbox allows the calculation in 2D of the optimal Transport distance. Moreover it includes Curvling constraints, that is imposing to the Diracs masses to be taken along a curve with a bounded speed and acceleration. We provide hands-on tutorials on the wiki.

The codes are released for Linux platforms (tested for Mint 18 Cinnamon 64-bit and Ubuntu 19.04 Disco Dingo).

The back-end computations are coded in C++ and make use of the computational geometry library CGAL and the linear algebra library Eigen3. We provide a python 3.7 interface by using the wrapper swig.
